Abstract :
We propose a novel ultrafast all-optical digital-to-analog conversion (DAC) scheme consisting of nonlinear optical loop mirrors, which can be applied to both a standard binary code and a Gray code. We conducted a proof-of-principle experiment and successfully demonstrated a 2-bit all-optical DAC with a Gray code, which indicates that the proposed scheme is feasible.
